The double angle formula is used to calculate sin 2x, cos 2x, tan 2x, for any given angle 'x'. The sine double angle formula for an angle 'x' is sin 2x = 2sin(x)cos(x).What is the Double Angle Formula? The double angle formula can find the value of twice an angle under sine...
Hence, cos 870° is equal to-√3/2. Problem 3 : Find the value of : (sin 780 sin 480° + cos 120° cos 60°) Solution : Let us find the value of each trigonometric ratio for the given angle. sin 780° = sin 60° =√3 / 2 sin 480° = sin 120° = sin (180° - 60°...

right triangle property for an angle equal to 30 degrees in the given right triangle. as we know two sides those are the length of the opposite side and hypotenuse but the third side is unknown i.e adjacent side. we need to find this side to find the value of cos 30 degrees. we ...
the values from 270 degrees to 360 degrees are always positive. To be accurate the value of cos 360 is 1. The function oftrigonometrythat relates an angle of the right-angled triangle to the ratio of sides is termed a trigonometric function. There are 6 trigonometric functions, sine, cosine...
